After trying Best Press, I don't want to use anything else for difficult wrinkles. Every day pressing, I'll do with steam or dry, depending on the situation. But for wrinkles that are stubborn, or for the crease left in where the fabric is folded on the bolt - or just the opposite, where I WANT a crease, Best Press works best for me.
That said, I don't recommend buying the small bottle locally... I buy the gallon sized refill online. Because I use it sparingly, a gallon will last at least me at least a year. Where a 16 oz. bottle is about $8, I hunt around for sales when I am getting low. If I'm persistent and patient, I can usually get a gallon, with free shipping, for about $40. Sometimes I have to buy two to get that price, so will go in w/ a friend. The cost is then about $.62/oz - much more reasonable and worth the cost.
